ARCH-READJUSTER.

Specification of Letters Patent.

Patented may 15, 1917.

Application filed July 31, 1916. Serial No. 112,324.

To all whom it may c oacc'rn Be it known that I, W ILLIAM Gnonen GRAY, a subject of the King of Great Britain, and resident of the city of St. John, in the Province of New Brunswick, Dominion of Canada, have invented certain new and useful Improvements in Arch-Readjusters, of which the following is a specification.

This invention relates to improvements in arch readjusters adapted to be utilized with foot-wear and the objects of the invention are to permit of the removable insole of a shoe being automatically adjusted to conform to the contour of the arch of the foot of the wearer of the shoe, to permit of adequate cushioning being given to the foot, so that liability of shock is entirely obviated, to simplify the construction of the arch readjuster and adapt the several parts of the same to better perform the func tions required of them, and it consists essentially of the improved construction, particularly described and set forth in the following specification and accompanying drawings forming part of the same.

In the drawings,

Figure 1 is a perspective view of the improved arch readjuster.

Fig. 2 is a longitudinal section of the same.

Fig. 3 is a transverse proved arch readjuster.

Like characters of reference refer to like parts in the several figures.

Referring to the drawings, A represents the improved arch readjuster, comprising the base plate 10 which is preferably made of metal and is so shaped that it may readily be inserted in a shoe, the said plate having the plates 11 and 12 secured thereto by rivets or the like.

The plates 11 and 12 are offset at their adjacent ends being substantially curvilinear and are adapted to slidably engage, so that when pressure is brought to bear on the same they may readily conform to the curvature of the foot.

The plate 12 is provided with an offset tongue 14 adapted to prevent lateral displacement of the spring 15 which is inserted between the base plate 10 and the said plate, the spring being held in engagement with the base plate by means of the section of the imoffset tongue 16 which engages with the lowest convolution of the spring.

The plate 11 is provided on that side, adjacent to the arch of the foot with a tongue 17 which is offset and adapted to slidably engage with the edge of the plate 12, the plate 11 being further provided with an angularly disposed flange 18, which in conjunction with said plate embraces the arch of the foot.

A leather covering or insole 19 is superimposed on the plates 11 and 12 and is rigidly secured to the former, so that when compression of the spring 15 takes place and the plates 11 and 12 are adjusted to conform with the said compression the said insole will readily slide over the plate 12, and there will be no liability of the insole bulging and becoming uncomfortable to the wearer.

The assembly of the arch readjuster, will be readily understood from the foregoing description.

When the arch readjuster is in use, any pressure on the insole 19 will cause the plates 11 and 12 to slide the one over the other, and the spring 15 will give an adequate cushioning and tend to counteract any liability of shock which would otherwise occur to the wearer.

From this description it will be seen that I have invented an arch readjuster which can be advantageously utilized with shoes to rectify defective arches, the simplicity of the readjuster being such that it will readily commend itself to the user.

As many changes could be made in the above construction and many apparently widely different embodiments of my in vention, within the scope of the claims, constructed without departing from the spirit or scope thereof, it is intended that all matter contained in the accompanying specifica'tion and drawings shall be interpreted as illustrative and not in a limiting sense.

What I claim as my invention is:

1. An arch readjuster comprising a base plate, a pair of superimposed curvilinear plates, slidably engaging at their adjacent ends and operatively mounted on the base plate, and resilient means 0 eratively supporting the said pair of p ates from the base plate.

2. A11 arch readjuster comprising a base plate, a pair of curvilinear plates having plate, a pair of curvilinear plates mounted their adjacent ends slidably engaging, the on the base plate, and slidably engaging at opposite ends being rigidly secured to the their adjacent ends, resilient means supbase plate, and a spring intermediate the porting the said plates from the base plate, said pair of plates and base plate. and an insole superimposed on the pair of 3. An arch readjuster comprising a base plates and rigidly secured to one of the plate, a pair of curvilinear plates mounted same.
